A Real-Time Measurement Algorithm for Available Bandwidth
Available bandwidth estimation is useful for route selection in overlay networks, QoS, and traffic engineering. Many measurement algorithms, such as Pathload, Pathchar, and Packet Transmission Rate (PTR) method, etc. have been proposed. PTR method sends a sequence of packet trains to characterize the interaction between probing packets and the competing traffic, and uses the average rate of the...
متن کاملAn Improved Available Bandwidth Measurement Algorithm based on Pathload
Available network bandwidth is an important metrics of the network performance. Quickly and accurately measuring the available network bandwidth is significant to network monitoring, congestion control, and network traffic projects. The traditional Pathload scheme for measuring the available network bandwidth suffers heavy measurement overheads and slow convergence. Based on the analysis of Pat...
متن کاملReal-Time Multi-path Tracking of Probabilistic Available Bandwidth
Applications such as traffic engineering and network provisioning can greatly benefit from knowing, in real time, what is the largest input rate at which it is possible to transmit on a given path without causing congestion. We consider a probabilistic formulation for available bandwidth where the user specifies the probability of achieving an output rate almost as large as the input rate. We a...
متن کاملA New Available Bandwidth Measurement Technique for Service Overlay Networks
We introduce a new measurement algorithm for the available bandwidth in a network path between two endhosts. This algorithm is an adaptation from existing active measurement methods for the purpose of being applied in inline network measurement. Inline network measurement method measures the available bandwidth by using packets which an active TCP connection transmits, instead of using probe pa...
متن کاملA Merged Inline Measurement Method for Capacity and Available Bandwidth
We have proposed a new TCP version, called ImTCP (Inline measurement TCP), in [1]. The ImTCP sender adjusts the transmission intervals of data packets, and then utilizes the arrival intervals of ACK packets for the available bandwidth estimation. This type of active measurement in a TCP connection (inline measurement) is preferred because it delivers measurement results that are as accurate as ...
